I'm new to ubuntu, and no very little of how it operates.

I downloaded and installed ubuntu 12.10 and everything seemed to work. My wireless connected without a hitch, but when I try to use an internet browser it won't load any pages. According to the computer, my "wireless" is still "connected" I'm just not getting any internet, except for right away for about 10 seconds after disconnecting and reconnecting. How do I get it to be a stable internet connection?

I'm going through a wireless router that is supplying stable internet to other devices, and to this one with windows on the other partition, so it's an ubuntu problem.

Help! I want to like Ubuntu, but if i can never do an internet search, it's a lost cause....
